About Windsor Insulation - Insulation Contractor in Windsor, CA

Windsor Insulation was founded in 2020 by a crew that had been doing insulation work across Sonoma County and wanted to build something closer to home. Windsor was the right fit - a growing town with a large share of homes from the 1990s and 2000s that needed attention, and a community that values working with people they know and trust.

The work here is familiar. Windsor homes are mostly wood-frame construction, built during the growth years after the town incorporated in 1992. Many of them were insulated to the standards of that era, which fall well short of what California requires today. Upgrading those homes - attics, crawl spaces, walls, and rim joists - is the core of what we do across 12 service areas in Sonoma County.

Sonoma County has also taught us that insulation is not just about energy bills. Wildfire smoke, damp winters, and clay soils that shift with the seasons all affect how a home performs. We take those local conditions seriously and bring that knowledge to every job. If you have questions about what your home might need, we are always happy to talk it through.
